Gyrating flying disc

ABSTRACT

A gyrating disc is disclosed having a circular and flat shape with an edge extending perpendicularly around its circumference. The gyrating disc has a weight on the interior or exterior of the edge, or between the center and the edge. When the gyrating disc is launched in a clockwise or counterclockwise manner, the disc achieves a gyrating flight, moving on its horizontal plane and stable at the vertical axis established in the center of the disc.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 62/391,566, filed May 4, 2016, entitled “GYRATING FLYING DISC,” which is incorporated herein by reference in its entirety.

FIELD OF INVENTION

Embodiments of the present invention generally relate to a flying disc and more particularly to a gyrating flying disc.

BACKGROUND

Flying discs are known objects of entertainment and are pervasively popular objects of game-play and amusement. Manipulation of physical properties of the flying discs may confer desirable variances in flight patterns such as, directional bias, velocity, and distance/height.

For example, Forti, et al. (U.S. Patent Pub. No. 2006/0250735) describes a cylinder with a pointed forward edge that edge allowing for a predictable distance of flight.

Creating a gyrating flying disc has been problematic. As described by Forti et al., (U.S. Pat. No. 5,816,880), gyrating flight can be accomplished with a cylinder-like hollow body having a leading and training edge where the leading edge is heavily weighted. This design, however, is devoid of a circular disc center, and fails to achieve desirable lift and curvature of flight. Moreover, the gyration achieved is only on the vertical axis, which is not advantageous.

Other designs include a weight on the leading edge of the disc, such as described in U.S. Pat. No. 3,590,518 to Ross. The weight, however, allows for a predetermined direction of flight. Because the leading edge is weighted, the disc effectively becomes a projectile. When launched, Ross' disc does not spin, but flies in the direction of the weighted leading edge. To facilitate launch, a separate launching device is provided. This design also includes a thickened center relative to edge, thereby diminishing the airfoil and lift achieved by the flying disc.

Still, other designs fail to achieve sustainable and predictable gyrating flight. As described in DE202005014916, a cavity within the disc holds sand, which when launched, disperses via the Coriolis Effect to the edge of the disc. Because the configurations of sand placement vary from throw to throw, a different flight pattern is achieved at each launch. This design also provides a hollow center, thus changing the dynamics of an airfoil achieved by a flying disc that is substantially uniform in thickness at its center.

A flying disc that consistently and yet preternaturally gyrates on both the vertical and horizontal axis is desired. A flying disc that gyrates and achieves flight in a spinning manner, launching from a point, and increasing in height before reaching an apex and descending is heretofore undescribed. Thus, there is a need for a flying disc that addresses the deficiencies of prior designs and provides a flying disc with an airfoil and weighted interior edge, which flies in a spinning motion with a reproducible gyrating motion from a launch, optionally reaching an apex before descent.

SUMMARY

Embodiments disclosed herein relate to a gyrating disc that is substantially circular and uniform in thickness at its center. Embodiments in accordance with the present invention further provide a gyrating disc with a curved edge, the curved edge and uniform center providing an airfoil for the achievement of sustained flight, and having a weighted portion.

Embodiments disclosed herein are further directed to a gyrating disc having a weight embedded within the interior edge, the exterior edge, or between the center and the edge.

In some embodiments, the weight comprises between about 16.5 to 21% of the weight of the total disc, and contained across between about 8% and 20% of the outer or inner circumference of the disc. The weight may alternatively be distributed between the center and the edge of the gyrating disc. The embodiments of the present invention provide for additional configurations of the gyrating disc as disclosed.

Embodiments in accordance with the present invention are directed to a gyrating disc which achieves a gyrating flight regardless of the orientation of the weight at launch.

Embodiments in accordance with the present invention are further directed to a gyrating disc wherein a maximum frequency of gyration is achieved when the launch originates from the weighted portion of the disc edge.

Yet other embodiments in accordance with the present invention are directed to a gyrating disc wherein distribution of the weight at the edge of the disc affects the frequency of the gyration, wherein a longer distribution of weight, occupying a larger percentage of the circumference has a lower gyrating frequency than a shorter, more concentrated weight, occupying a smaller percentage of the circumference of the gyrating disc.

In other embodiments of the present invention, the gyrating disc comprises a rigid disc of uniform thickness and having a curved edge.

In some embodiments of the present invention, the gyrating disc comprising a curved edge embedded with a weight of a dimension and magnitude so as to effect a gyrating flight when the disc is launched with either a clockwise or counterclockwise spin.

These and other advantages will be apparent from the present application of the embodiments described herein.

FIG. 1 illustrates a top view of the gyrating disc. The disc is substantially circular in shape. When viewed in the top orientation, the uniformity of the disc is apparent. The disc comprises a center 100 and an edge 101. The gyrating disc can be comprised of a variety of materials including rubber, fabric, plastic, resin, natural and/or synthetic polymers, vinyl, fiberglass, and/or any mixtures thereof. In one preferred embodiment, the gyrating disc is comprised of polyethylene. The gyrating disc may be manufactured in multiple ways. In one embodiment, the gyrating disc is entirely manufactured through injection molding. In other embodiments the weight of the disc is manufactured separately from circular disc and edge, discussed below. While the gyrating disc in one preferred embodiment is rigid, a flexible disc is also contemplated.

FIG. 2 illustrates a bottom view of the gyrating disc. From this perspective, the weight 102 can be seen. As shown in FIG. 2, the weight 102 may be placed adjacent to the edge 101 of the gyrating disc. In some embodiments, the weight 102 is placed on the outer edge 101 of the gyrating disc. In other embodiments, the weight 102 is placed on the inner edge 101 of the gyrating disc. In yet other embodiments, the weight 102 is placed between the center 100 and edge 101 of the gyrating disc. The weight 102 can be comprised of any manner of materials, including: clay, putty, plastic, resin, natural and/or synthetic polymers, vinyl, fiberglass, and/or any mixtures thereof. In some embodiments, the weight 102 is fabricated of the same material as the gyrating disc's center 100 and edge 101. In some embodiments, the weight 102 is secured to the gyrating disc by any type of adhesive, including glues, and the like. In a preferred embodiment, the weight 102 is injection molded as one piece with the center 100 and edge 101. Without the weight 102, the disc is substantially uniform in thickness from the center 100 to the edge 101. In yet other embodiments, the gyrating disc is made from one piece (e.g., injection molding).

FIGS. 3A, 3B, and 3C illustrate three alternate embodiments of the gyrating disc, as viewed from the bottom. In these views, it is apparent the weight 102 may vary in distribution and in size. In the embodiment illustrated by FIG. 3A, the weight 102 is longer throughout the edge 101 relative to the embodiments illustrated in FIG. 2 and FIG. 3B. In some embodiments, the gyrating disc is approximately 31 inches in circumference, and 10 inches in diameter. The gyrating disc can be made in any size (e.g., from 2-100 inches in diameter). In FIG. 3A, the weight 102 is dispersed across approximately 16% of the circumference of the gyrating disc (i.e., wherein the disc edge 101 is 31 inches in circumference, the weight is distributed 5 inches within that circumference). In FIG. 3B, the weight 102 occupies a smaller portion of the interior edge 101, about 12% (i.e., wherein the disc edge 101 is 31 inches in circumference, the weight is distributed 3.8 inches within that circumference). Other embodiments with weights occupying varying percentages of the edge are contemplated, and do not depart from the scope of the present invention. For instance, the weight could be distributed amongst 10%, 14%, 18%, or at any value between 8% and 20%. The proportion of weight 102 to the circumference of the edge 101 is maintained when scaling up or down for size. While the weight 102 is shown in an elongated shape in FIGS. 3A and 3B, it is contemplated that the weight 102 may be more circular in shape, as depicted in FIG. 2. FIG. 3C illustrates the gyrating disc as manufactured in one piece. In this embodiment, it is apparent that the weight 102 is integrated within the edge 101 and center 101. FIG. 3D illustrates the gyrating disc from a top view, illustrating a weight 102 on the outer edge 101 of the gyrating disc, as in one embodiment. Moreover, other shapes such as rectangular, polygonal, or oval are contemplated and do not depart from the scope of the present invention. The weight 102 may further be shaped so as to be ergonomic for facilitating launch with a spinning motion.

In FIGS. 2, 3A, 3B, 3C, and 3D the magnitude of the weight is similar. In one preferred embodiment the weight is approximately 30 grams, and the disc is approximately 147 grams. In other embodiments, the weight is approximately 20% of the weight of the disc, or 18.8% of the total weight. In yet other embodiments the weight comprises between 16.5-21% of the total weight of the gyrating disc. Where the weight 102 is distributed over a larger portion of the edge 101, as seen in FIG. 3A, a slower frequency of gyration is achieved.

FIG. 4 illustrates an isometric view of the gyrating disc. From this perspective, the shape of the edge 101 can be appreciated. The edge 101 is curved in shape and substantially perpendicular to the center 100, and extends to create an overall dome-like shape of the gyrating disc. In one preferred embodiment, the edge 101 is substantially perpendicular to the center 100 of the disc, and extends approximately 1 inch relative to the center 100 of the gyrating disc. In other embodiments the edge extends between 0.5 and 1.5 inches.

FIG. 5 is an illustration of a user launching the gyrating disc, in accordance with an embodiment of the present invention. Launching the gyrating disc with a spinning motion 103 (i.e., counterclockwise or clockwise), while holding onto the weight 102 results in an optimum frequency of gyration, though gyrational flight is achieved regardless of weight orientation at launch. The gyrating disc is thrown with a spinning motion, the flight of the disc having a launch point, an apex, and a descent. While rotating in flight, the gyrating disc moves in a horizontal plane 104, with a stable vertical axis at the center of the gyrating disc. The solid center 100 and edge 101 of the gyrating disc allow for advantageous lift when launched in a spinning manner, where air moving over the top of the gyrating disc will move faster relative to the air under the disc. The momentum of the spin at launch gives the gyrating disc orientational stability by allowing the gyrating disc to receive a steady lift from the air as the gyrating disc passes through it. A launch with greater spin will increase stability of flight and increase the frequency of gyration.

FIG. 6 illustrates a top view of the gyrating disc after launch. The disc is launched with the spin in FIG. 5, 103, and oscillates on the horizontal plane 104 as it flies through the air. As stated above, the magnitude and distribution of the weight 102 as well as the momentum of the spin 103 at launch will alter the frequency of oscillation. A larger weight, with a smaller distribution, and a high spin 103 at launch will facilitate maximum gyration during flight.
